CASH DRAWER.

Application tiled April 17, 1922.

The invention relates to a cash drawer combined with an adding machine, or other recording or accounting apparatus; and the object or the improvement is to provide releasing mechanism by which the cash drawer` may be opened by a recording operation oit the adding machine.

Cash drawers are frequently provided with locking means combined with spring means arranged to automatically open the drawer when the loclr` is released, and adding machines are provided with a handle or lever for operating the recording mechanism.

By the present improvement the releasing mechanism includes spring controlled plunger post means which can be shifted from an operating position to release the cash drawer lock by each recording operation of the adding machine, to an inoperative position wherein the lock will not be released by operation o't the adding machine; which may be supplemented by means for stopping the releasing means in inoperative position. A

An embodiment of the invention is illustrated in the accompanying drawings, forming part hereof, in which*- Figure I is a side elevation of an adding machine mounted on a case having a cash drawer therein, the side of the adding machines being broken away and the cash draw` er being shown in longitudinal section, as on line 1-L Fig. 11;

Fig. Il, a front elevation ot the same, showing the improved mechanism in cross sectio-n, as on line T12-TL Fig. I;

Fig. lll, a longitudinal section of the case and rear part of the cash drawer, as on line lll-lll, Figs. 11 and 1V;

Fig. 1V, a bottom plan View of a cash drawer case, without the cash drawer therein, showing the arrangement of the lock and release mechanism in the top thereof;

Fig. V, a perspective view of the releasing mechanism and co--operating parts ot' the adding machine and release stopping mechanism;

Fig. V1, a perspective view of the cash drawer locking mechanism; and

Fig. VII, a fragmentary cross section as on line Ill-I1, Fig. l, showing the intermediate mechanism shifted to inoperative position.

Similar numerals refer to similar parts throughout the drawings.

Anadding machine 1 may be mounted serial I0. 554,310.

upon a ease 2 containing a cash drawer 3; and thecash drawer may be provided with longitudinal flanges 4l on each side adapted to ride upon rollers 5 or slide upon flanges 6 underneath a roller 7 mounted in each side of the case.

A conical spiral compression spring 8 mounted in the rear end of the case, is adapted to be compressed by the rear end of the cash drawer when the same is pushed rearA ward into 'the oase, and a lock plate holding member 9 mounted on the rear end of the drawer is provided with an aperture 10 for receiving a bolt latch member 11 to lock the drawer in closed position.

The bolt 11 protrudes downward through a guide opening 12 in the bottom plate 13 ot a bracket 14; securedl to the topy of the case, and the bolt is pivotally connected to the rear end of a roclt arm 15 secured to a rook shaft 16 journaled in bearing brackets 17 and 17. The rock shaft is pinvided with a eranlr arm 18 pivoted to a connecting bar 19 extending forward in the case, and also connected with an expansion spring 2O secured to the rear end ot' the case acting to hold the lock bolt downward in engagement with the loclr plate.

The rear end of' the leek plate is beveled downward and the lower end of the loelr bolt is correspondingly beveled, so that when the drawer is pushed inward the bolt will be pushed upward against the action of the spring 2O until it enters the aperture in the lock plate, into which it is pushed downward by action of the same spring; and at the same time the conical spring 8 is compressed by the rear end of the drawer, so as to push the drawer forward whenever the lock bolt is released from the loclr plate.

The forward end of the connecting bar 19 is pivoted to the upper arm 21 of a bell crank tulcrumed on a spindle 22 carried by a bracket 23 secured to the top of the case. The lower arm 24 ot the bell cranlr extends forward under the lower end oi the lock releasing plunger post 25, as shown in Fig. V.

The releasing plunger post 25 is mounted for up and down sliding operation in a guide barrel Q6, wherein it is normally held upward by a coiled spring Q7 located around a reduced portion 28 of the plunger between the bottom of the barrel and a shoulder 29 at the upper end of the reduced portion.

The guide barrel is secured in an aperture CIT 30 in a plate 3l mounted for sliding in a transverse guide way 32 secured to the top of the case. The bottom 33 of the guide way is provided with a transverse slot 34, and the top of the case is provided with a corresponding slot 35, through which the guide barrel 26 for the releasing plunger post depends downward.

This construction and arrangement permits a limited transverse sliding of the slide plate 3l in the guide way, so that the release plunger post may be moved inward from its normal position directly over the arm 24 of the bell crank, to a position clear of the inner side of the same.

The parts are arranged so that by pushing the plunger post downward when in normal position it will push the forward arm of the bell crank downward and operate the releasing mechanism to withdraw and disengage the lock bolt from the loclr plate, but that when the releasing plunger post is shifted inward it may be pushed downward without impinging the arm of the bell crank and will not operate the lock releasing mechanism, thus preventing the drawer from being opened by abnormal means. i

Means for stopping the releasing plunger post in its shifted or inoperative position may include a bell crank 36 operating on a vertical fulcrum 37 secured within the case of the cash drawer. One arm 38 of the bell crank extends rearward past the outer side of the releasing plunger post guide barrel, and the other arm 39 extends laterally in rear of the bolt 40 of a lock 41.

The stopping means are arranged so that when the stop boltis withdrawn, the bell crank is free to swing and permit the releasing plunger post to move outward into operative position, as shown by full lines in Fig. V, but that when the releasing plunger is shifted inward to inoperative position, the stopping bolt may be operated against the lateral arm of the bell crank and bring its rear arm against the outer side of the releasing plunger post guide barrel and stop the same from being shifted outward into operative posie tion.

The transverse operating shaft 42 of the adding machine is located adjacent to the rear side of the releasing plunger post, the upper end of which extends upward in front of the shaft; and upon the shaft is secured a roclr arm 43, which may be in the form of a flange or plate, so located that its forward edge 44 will operate as a cam against the upper end of the releasing plunger post- 25, when the same is in normal position, and will push the same downward to actuate the lock releasing mech-A anism. By these means, the cash drawer lock will be released every time a record is made on the adding machine by swinging its op erating arm 45 forward in usual manner. i

ln the normal operation of the releasing mechanism the bolt of the stop lock is withdrawn by use of an ordinary key, and the releasing plunger post is moved outward in the guide way by means of a handle post 46 on the outer end of the slide plate, to bring the releasing plunger post in the path of the rocll: arm 43, so that the cash drawer will be automatically opened every time the adding machine is operated.

`l/Vhen, however, it is desired to operate the adding machine without opening the cash drawer, the releasing plunger post is pushed inward so that it will not be acted upon by the rock arm, and if it is desired to stop and lool: the releasing plunger post in inoperative position, the bolt of the stop lock is operated by a key to swing the stop arm of the bell crank 3G against the outer side of the releasing plunger.
